It's been awhile since I've done this but I think that D is the answer hope this helps
A linear function is usually in the form: y=Mx+c. In equation 1, there is no x term and same for equation 3, leaving your only and correct answer to be equation 2. And if you rearrange equation 2, you will get: 5y = -2x + 8.

Answer: Proportional
Step-by-step explanation: To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship
